【Task】 The present invention is to provide a capacitor having a large capacitance per volume and exhibiting excellent high voltage resistance and safety even in a high temperature atmosphere of 80 ° C. or higher, and a material therefor. [Solution] A polypropylene film composed of a polypropylene resin mainly composed of propylene, wherein at least one surface of the film surface has a base layer composed of satin-like irregularities, and the 10-point average roughness (Rz) of the surface is 0.5. Provided are a metallized biaxially oriented polypropylene film having a metallized layer provided on at least one side of a biaxially oriented polypropylene film characterized by having a surface gloss of 90 to 135% and a capacitor comprising the same. .
